244 REPORT OF COMMISSIONER OF FISH AND FISHERIES. [34] 



urements of this arm, as then preserved. It had contracted excessively 

 in the alcohol, and was only 13" feet 1 inch in length (instead of 19 

 feet, its original length), the enlarged sucker-bearing portion being 27 

 inches; the large suckers occupied 12 inches; the terminal part bear- 

 ing small suckers, 9 inches; circumference of slender portion, 3.5 to 4.25 

 inches ; of largest part, 6 inches ; breadth of face, among large suckers, 

 2.5 inches; from face to back, 1.C2 inches ; diameter of largest suckers 

 outside, .75 of an inch ; aperture, .63 of an inch. It will be evident 

 from these measurements, when compared with those made while fresh 

 and from the photograph, that the shrinkage had been chiefly in length, 

 the thickness remaining about the same, but the suckers (which had 

 lost their horny rims, and therefore their size and form) were consid- 

 erably smaller than the dimensions previously given. Comparing all 

 these dimensions with those of the Logie Bay specimen, and calculating 

 the proportions as nearly as possible, it follows that this specimen was 

 very nearly one-third larger than the latter, but the large suckers ap- 

 pear to have been relatively smaller, for they were hardly one-twelfth 

 larger than in the Logie Bay specimen. As the relative size of the large 

 suckers is a variable sexual character in certain species of squids, it is 

 possible that the difference may be a sexual one in this case. 



A few of the horny rings from the small distal and lateral suckers 

 (Plate IV, figs. 3, 3 a) were sent to me by Mr. Harvey. These agree 

 well with the corresponding suckers of No. 5. 



To this species I formerly referred the jaws and two large suckers 

 from the 'club' of the tentacular arms of the Bouavista Bay specimen 

 (No. 4, see p. 8). In form, size, and proportions the jaws resemble 

 those of the specimen (No. 5) described above, so that the size of these 

 two individuals must have been about the same. These jaws had been 

 dried, and were very badly broken when received, so that only part of 

 their dimensions could be ascertained at first, but I have recently par- 

 tially repaired them, so as to study them more fully (see table under A. 

 princeps). The total length of the upper mandible was about 105 mm ; 

 tip of beak to notch, 16 mm ; notch to end of proper cutting edge of alae, 

 75"™. Tlie ] ower m andible (Plate III, figs. 4, 4 a) shows both sides of 

 the rostrum and alae. The notch and tooth are well marked, and the 

 tooth in front of it is narrower and much more elevated on one side 

 than on the other. It is, therefore, quite possible that it belongs to A. 

 princeps. The suckers (Plate IV, figs. 1, 1 a) had been dried, and 

 have lost their true form, but the marginal rings are perfect, and only 

 23.4 mra (.92 of an inch) in diameter, but though somewhat smaller than 

 in the specimen just described, they have the same kind of denticula- 

 tion around the margin. Their smaller size may indicate that the speci- 

 men was a male, but they may not have been the largest of those on 

 the tentacular arm. 



To this species I also refer a young specimen (No. 24) which was 

 found floating at the surface, at the Grand Bank of Newfoundland,
